Abstract
The general field of the invention is that of methods of representing a cartographic image in a geolocated synthetic vision system for vehicles, said system including a cartographic database, geolocation means, graphic generation means enabling generation of a two-dimensional or three-dimensional synthetic view of said terrain, and a display device. In the method in accordance with the invention, the angular position of each point of the synthetic view is known with an angular error depending on the distance of said vehicle and the accuracy of geolocation of said vehicle, if said angular error is less than or equal to a predetermined angular tolerance, the point is represented in a standard representation mode and if said angular error is greater than a predetermined angular tolerance, the point is represented in an uncertainty representation mode different from the standard representation mode. The applications are preferably aeronautical.
